There are cases when sizeof(int) == sizeof(long) == sizeof(size_t). On
such cases however int and long are incompatible types in theory. We
should not assume typedef long size_t, because on Solaris size_t is
actually a typedef of int.
This reduces compiler warnings on such situations.
With these macros implemented we can write codes just like we can assume
the compiler being clang. MSC_VERSION_SINCE is defined to implement
those macros, but turned out to be handy for other places. The -fdeclspec
compiler flag is necessary for clang to properly handle __has_declspec().
This macro shall be shared among other files, not just for mjit.c.

* ruby_atomic.h (ATOMIC_CAS): old value to be swapped should be
same as the destination. immediate value may need type
promotion.

* ruby_atomic.h (ATOMIC_SIZE_CAS): fix the argument order of
InterlockedCompareExchange64. new value and then old value is
the last.

__sync family are legacy functions now and it is recommended
that new code use the __atomic functions.
